Daryn Sharp commented on MAPREDUCE-2568:
----------------------------------------

Yes, I think you are right.  I misspoke on the other jira because I didn't 
remember that a number of commands already used CommandFormat.  I suspect 
people aren't going to be fond of losing the gnu permute behavior...  Should I 
make permute be an option for CommandFormat with a default of on?  It would 
have to be an option since all commands use CommandFormat now, and some like 
"test" cannot tolerate permute.

> CommandFormat which is used to parse command lines is following posix 
> conventions of stopping at the first non-argument.  There is just one test in 
> this file which placed an option in the middle of the args.
